Luminary Micro Compact Specimen Photoexcitation System

Up to 3 W peak power
Tight focusing (<40 µm FWHM)
Temporal profile from µs to s
Remote control of focus position, laser power, pulse duration
Extremely compact footprint
No sacrifice for the freedom of choice of specimen holders

Luminary Micro is a Compact Specimen Photoexcitation System (CPXS) for JEOL TEMs.
It is composed of a modulated laser, a compact optical delivery system (µODS), an inlet port, and a mirror. With this add-on, users can direct and focus the laser output onto the TEM sample in situ.
The Luminary Micro can induce a rich variety of reactions and dynamic processes in the specimen, thanks to its focus size <40 µm FWHM, adjustable peak power up to 3 W, and the modulated pulse widths ranging from a few microseconds to seconds. With the Luminary Micro, users can study laser-induced phenomena in situ using fast cameras.
Combined with IDES/JEOL EDM fast shutter and/or Relativity subframing systems, Luminary Micro allows users to perform time-resolved studies using pump-probe methods in the microsecond time scale. Its footprint is extremely compact, and it can be easily installed without affecting the TEM resolution, yet it does not sacrifice the freedom of choice of specimen holders.
